"Post-natal depression not taken seriously"

I went to the GP regarding depression and anxiety I've been having since my first baby was born. I told them that I thought I might have postnatal depression. The GP told me that they don't use the term postnatal depression for men, that's just for women as it is do with hormonal changes. However, the National Childcare Trust says "Postnatal depression can affect dads too" and "Just as with mums, changes in hormones might make postnatal depression in dads more likely".

So having told me my condition didn't really exist, the GP went on to say that my mental health would improve now, as 3 months is the age where babies sleep better, and I'll feel better with better sleep. But again, the NCT says "The peak time for postnatal depression in men is three to six months after the birth", so statistically this is when it is likely to get really bad for me.

So, okay, the GP was ill-informed and dismissive of PND in dads. But they could still do the standard mental health checks and get me to fill in a questionnaire to evaluate how serious my depression is and judge my suicide risk (e.g. PHQ 9) - I've had depression in the past and know that is a completely routine precaution.

The GP asked no such questions - formally or informally. If I had been at risk of suicide, the GP did nothing to make sure I got help. They dismissed my health concerns and made me feel like I couldn't open up to them. It was a really bad level of care, and I am very disappointed.
